Abstract:
BACKGROUND: Home-use devices designed for cosmetic purposes have recently gained popularity. Small, low-energy, low-cost intense pulsed light (IPL) systems provide safe, convenient, and private treatment for several medical conditions. OBJECTIVE: In this study, we aimed to assess the efficacy and safety of a home-use IPL device for hair removal, acne treatment, achieving a whitening effect for hyperpigmentation, and wrinkle reduction. METHODS: Five IPL hair removal treatment sessions were performed at 1-week intervals. A total of 10 sessions were performed in a split-face manner for other medical conditions. Four independent randomized controlled trials were performed using a blind evaluation method. All subjects were followed up twice to evaluate the maintenance of efficacy. RESULTS: A significant reduction in hair was observed via trichoscopy following two sessions of treatment (p<0.001). A mean hair reduction of 80% was observed at week 4; however this returned to the previous state upon cessation of treatment. Acne grading decreased from 2.6 to 1.1 at week 8, and IPL treatment induced a significant reduction in melanin index after 2 weeks. The average values of the difference of R2 (Cutometer(R)) between IPL-treated areas and baseline were higher than those of the difference of R2 between control area and baseline. CONCLUSION: This home-use IPL device was effective for hair removal and treatment of acne, hyperpigmentation, and wrinkles.
